GRE PASS THROUGH ASA

Hi all, I am new to the forum therefore forgive me if i have placed this post in the incorrect area.

I have been given the task of configuring an ASA to pass GRE traffic to an SBS which is dealing with Routing and Remote Access / PPTP vnp connections.

The customer i am doing this for only has a single public IP address i therefore i plan to use the commands below

ASA(config)# static (inside,outside) tcp interface 1723 192.168.1.3 1723 netmask 255.255.255.255

ASA(config)# access-list outside_access_in extended permit tcp any interface outside eq 1723

ASA(config)# access-list outside_access_in extended permit gre any interface outside

Is there anything in addition to the above i should be aware of?

Also to add to the scenario, there is a Cisco 800 doing all the routing which I have been told is port forwarding ALL ports to the ASA. So my next quetion is DOES THE CISCO 800 REQUIRE ANY CONFIGURATION?

Hope this is clear?

Thanks in advance.

Wayne
